STRAIN-INSULATUR SIGN.

Apphcation filed T/Iay To (/71 7073077), it may concern.

i=1i1--tiiN a citizen of the United States, and a resident of lfest View. in the county of Al egheny and State of Pennsylvania. have made a new and useful lnyention in Strainlusulator Q oie'n, of which the following is a SpQClilGfitlfiIl.

ln power line transmission, charged Wires are often upheld by supporting Wires attached to poles. This necessitates the use of insulating; means to prove .t the groundin o t the current. A familiar illustration or this is the support of trolley wires by cross Wires to poles located at the street curb. The circuit may be brolren by dividing the supporting; wire between the trolley wireand each pole and securing the divided parts to an insulator so that the Wires have no contact with each other. his is in addition to any other insulating means between the trolley Wire and supporting Wire.

Signs indicatingyoltage, (hing er.v location o'li car stops circuit breaks and other in torniatioi'i are commonly used in connection with power lines and are formed oi? metal or wood panels and means securing: same to the pole or Wire and are very likely to h L1 ear to the point where a strain insulator is attached.

My invention consists or" a coni'iecting unit for oppositely pulling Wires combining the limctious of connecting and insulating the contiguous Wires and giyin any desired int ation. it may be inanutactured or {25h porcelaiin Wood or other insulating material and may be of any suitahle shape. preferred form is illustrated in -drawi111? toruhngg; a part of this specification in which l lfjf llfi 1 is a side elevation of my strain insu itor; 2 is a section through same on line 2-2 oi E ie. 1 .d Fig. ii illusits application to a trolley line for Z. he body l of the insulator is provided with a wu'l'ical hole and extending from the ends of this hole are grooves i0 on the top and bottom of the body. Horizontal Specification of Letters Patent.

hi es 6, spaced from each other and from i hole 5, extend through body 4 and one pair ot adjacent ends of holes 6 are connected by a groove 11.

Hole 5 and grooves 10 are adapted to accommodate the looped end of a Wire such as WllO 7 in F 3. Holes (3 and groove 11 are similarly adapted for the loo ed end of an opposing Wire such as Wire 8 in Fig. 3. Each wire will be securely held spaced from the other so there can he no contact between them.

Integral with body 1 are flanges 9 of a shape and size adapted to bear Words of no tice or at *ertisement which may he read at sufl'icient distance to serve a useful purpose. I pret'er to engrave the letters of the sign in the flange lace and coat the engraved letters with enamel.

have shown two opposite flanges in the rred term of my invention but when is shown in Fig. 3 only one flange necessary. ()bviously, any number langes could be used at Various angles to each other and either above or be low as Well at the sides of the body of the insulator.

T his device may be manufactured more economically than the separate articles now used for the some purposes, it reduces the expense ot installing and it avoids metallic hangers, or other attaching means as used on ordinary signs which are subject to corrosion, electrolysis and other disintegrating influences.

l claim:

in article of manufacture comprising a substantially larger dimen suhserioed my name this 8th day of April, 1919.
